Oracle Linux is the same as Red Hat Linux!
Only better!
So use the Oracle Linux and use YUM!
Easier!

How to grow a Oracle Linux disk drive when you run out of space

Extending partitions on a Linux virtual machine hosted in Oracle VM Server
Here is how I did it ,
I use
Oracle VM Server Oracle VM server release 3.2.2
Oracle VM Manager Version: 3.2.2.520
Shutdown the VM
Navigate to VM Machines Oracle VM Home > Servers and VMs > Server Pools >> Stop
Edit VM
Navigate to VM Machines Oracle VM Home > Servers and VMs > Server Pools >> Edit
On the Disk Tab - Select the hard disk you would like to extend
Update the required size, Click OK
Start the VM
ssh to vm and Log in as root
Use fdisk to find out the info At the command prompt type fdisk -l
[root@vmgdbwlnchs01 ~]# fdisk -l
Disk /dev/hda: 69.7 GB, 69793218560 bytes
255 heads, 63 sectors/track, 8485 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/hda1 * 1 13 104391 83 Linux
/dev/hda2 14 6527 52323705 8e Linux LVM
Disk /dev/dm-0: 47.3 GB, 47311749120 bytes
255 heads, 63 sectors/track, 5751 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk /dev/dm-0 doesn't contain a valid partition table
Disk /dev/dm-1: 6241 MB, 6241124352 bytes
255 heads, 63 sectors/track, 758 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk /dev/dm-1 doesn't contain a valid partition table
The response should say something like Disk /dev/hda: 69.7 GB, 69793218560 bytes
At the command prompt type fdisk /dev/hda.
Type p to print the partition table and press Enter
Type n to add a new partition
Type p again to make it a primary partition
Now you'll be prompted to pick the first cylinder which will most likely come at the end of your last partition
Type w to save these changes
[root@vmgdbwlnchs01 ~]# fdisk /dev/hda
The number of cylinders for this disk is set to 8485.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
(e.g., DOS FDISK, OS/2 FDISK)
Command (m for help): p

The partition table has been altered!
Calling ioctl() to re-read partition table.
WARNING: Re-reading the partition table failed with error 16: Device or resource busy.
The kernel still uses the old table.
The new table will be used at the next reboot.

At the command prompt type fdisk -l. You'll notice another partition is present. initialize this new partition as a physical volume using pvcreate

Extend the logical volume by the amount of free space (on the command line use a digit less, else you might see Insufficient free space Here i am using 14.95, though it shows me 14.97 above))
